Summary: After his death at the end of the Fourth Great Shinobi War, Uchiha Sasuke is offered the chance to be reborn into a different world to help free it from the oppression of an individual known as the "Demon King". Eager to seek atonement for the crimes he committed in his past life, Sasuke accepts the offer without hesitation, a decision he might just come to regret.

Edit: Some minor grammatic and spelling errors have been corrected, and an honorific has been added when Eris refers to Sasuke by name.

Chapter I: A Chance for Redemption

From the moment he had challenged his rival to one last fight, he had known that he most likely wouldn't survive the encounter. Heck, he had even hoped that he wouldn't survive the encounter. He knew that even if he did survive, there could be no future for him, no place in the world that would rise from the ashes of the war that he had helped start.

By the time he had found his resolve to side with the Allied Shinobi Forces in their effort to stop Madara and the Akatsuki, he had already allowed his thirst for vengeance to drive him past the point of no return. And so, he had resolved to die at the hands of his best friend in the hopes that Naruto would earn recognition as the true hero of the Fourth Great Shinobi War, just like his brother had died in the hope that Sasuke himself would earn recognition as the hero who avenged the Uchiha Clan's murder. It was almost poetic in a way.

And that was how he had ended up... wherever it was he currently found himself. He was seated on a small chair, surrounded on all sides by an impenetrable black void. Opposite to him, another chair had been placed, though this one was empty and looked a bit more extravagant compared to the simple chair where Sasuke himself was seated, with a high backrest and intricate designs running down its' sides. To say that Sasuke was confused by this strange turn of events would be an understatement. Given the way that the shinobi who had been revived through the Reanimation Jutsu had talked about their experience with death, he had expected that his consciousness would simply end at the time of his death and he would cease to exist.

"Uchiha Sasuke?" a soft voice asked from somewhere behind him, causing Sasuke to stiffen and turn his head around so fast that a normal human would've gotten whiplash from the sudden movement.

Standing a few feet behind him was a young girl who appeared to be around his age, with dark blue eyes and a mane of silvery white hair that ran far down her back, almost like a cape of some sort. The girl was dressed in an outfit consisting mainly of dark blue and white with intricate golden details, complete with a dark blue headpiece. She was slightly out of breath and appeared harmless enough, but there was something about her that put Sasuke on edge. Like how she had managed to sneak up on him without him noticing her presence.

"Who's asking?" he asked warily while he slowly rose to his feet and turned around to face her, just in case she tried anything. A part of him was telling him that he was overreacting, as the girl didn't look like she had a bad bone in her body, but life as a missing-nin had taught him to never judge a book by its' cover. She didn't seem to be put off by his guarded behavior though, as she just offered him a nervous smile and straightened up.

"Ah, my apologies," she spoke as she approached him. "My name is Eris. In some worlds, I am known as the Goddess of Fortune."

Whatever answer Sasuke had expected from the girl, a claim to godhood certainly wasn't it. Upon hearing the outrageous claim, the Uchiha couldn't help but let out an indiscreet snort of disbelief, though he caught himself quickly enough to almost disguise it as a cough. Almost.

"Really?" he said as the self-proclaimed goddess walked past him towards the ornate chair that had been placed opposite to his own. "So am I to assume that you're here to judge me and send me on my way then?"

Seeing as Sasuke had never been one to believe in any kind of divinity, he didn't even bother to hide his skepticism at the girl's claim. Eris, however, took his attitude in stride and didn't appear bothered at all by his obvious disbelief as she took her place opposite to him. Instead, she simply offered him a serene smile.

"Well, I could if that is what you wish," she said. "However, if that was the only thing I could offer you, then you wouldn't even be here in the first place, Sasuke-san."

The 'goddess' left that statement hanging in the air as if trying to build up the tension for a big reveal. While Sasuke was still skeptical about Eris' claim to godhood, he figured he didn't have anything to lose by going along with it for now. He was already dead, after all.

"And what else, if I may ask, would you be able to offer me?" he voiced the question he knew she wanted him to ask.

Upon hearing the question, Eris' smile seemed to slip from her face to be replaced by a solemn expression that caused Sasuke to narrow his eyes in annoyance. He had always hated it when people pitied him. It made him feel small, almost as if the person who was pitying him was looking down on him.

"I can offer you a chance to redeem yourself."

The words seemed to echo in his head as if they had been spoken to him from the other end of a long tunnel. For a brief second, Sasuke's eyes widened as the meaning of the words sunk in, before his entire body tensed up like an animal ready to pounce. Before he could voice his outrage at the very thought that he could have any chance at redemption after what he'd done, that no matter what he did there was no way that anyone across the Elemental Nations and beyond would ever view him as anything but a villain, Eris held up a hand to keep him from interrupting her. And surprisingly, Sasuke found himself obliged to her silent request.

'No,' he thought as he slowly slid back into his seat. 'It wasn't a request as much as it was an order.' For a brief moment, there had been an unnatural intensity to the white-haired girl's gaze, and her gentle aura had been replaced by another presence entirely. A presence worthy of a god.

"I know what you have done, Sasuke. And perhaps in the eyes of your world, you never will be anything but a villain to be defeated, an obstacle to be overcome." Eris said as her face melted back into the solemn expression it had held before and her divine presence faded away. "But everyone deserves a chance for atonement. And if your world can't give it to you, then perhaps you could seek it in another?"

It took a few seconds for Sasuke's mind to catch on to what the goddess was telling him, but once it did he did a double take.

"You're sending me to another world?" he asked in shock. Given Team Seven's recent battle with Kaguya, it wasn't exactly a revelation to him that there existed other worlds besides his own. However, it had never occurred to him that there could be other worlds out there inhabited by humans, or something akin to it. In his defense, he had been a bit busy fighting to save himself and life as they knew it to really give it much thought, but that was beside the point.

"Only if you accept my offer," Eris said, her smile softening slightly at his shocked expression and the slight twitching of her lips gave Sasuke the impression that she was trying to suppress a giggle at his reaction. "The world from which I hail is facing a terrible crisis at the hands of an individual known as the Demon King. With the situation getting worse every day, people who die refuse to be reborn into the world and thus the population is steadily declining. That's why I'm offering you this chance to be reborn into our world and help us in our time of need!"

All throughout her monologue, Sasuke had noticed that Eris appeared to steadily be growing more excited as she kept talking about what she was offering him. By the time she was finished, she had leaned forward slightly in her chair and her holy facade had slipped to reveal a hopeful glint in her eyes. Kind of odd for a goddess talking about the suffering of her people...

"Hold on, back up a second. What do you mean "people refuse to be reborn"?" he asked tentatively.

And just like that, the facade had been cracked.

"Eh? I didn't explain that already?" Eris asked, blinking in confusion.

When Sasuke shook his head in response, the girl's cheeks immediately began to heat up in embarrassment. Gone was the gentle and authoritative goddess and in her place was an embarrassed teenage girl shaking her head and hugging her arms over her chest, whispering incoherently to herself, of which Sasuke could only catch snippets.

"...messed up... first time... so embarrassing... Aqua-senpai would laugh at me..."

-X-X-X-X-X-

"So hypothetically, how would this 'reincarnation' into your world interact with a Reanimation Jutsu if someone attempted to summon me back from the dead in my world?" Sasuke asked once they had gotten the discussion back on track. Apparently, this was Eris' first time guiding someone to the afterlife, after the goddess that had previously been entrusted with the task had 'taken on other responsibilities', and she had really wanted to do well on her first time.

"Well, as far as we can tell, they wouldn't be able to. It's impossible to know for certain since this is the first time we've picked someone from your world, but from what we can tell, accepting our offer would be equivalent to being sealed by the Shinigami in your world." Eris' explained, her cheeks still tinged a little pink from her little episode.

Sasuke hummed in thought, quietly mulling over what she had told him so far. Basically, Eris' world needed someone strong to help her people fight back against this Demon King fellow, and his only other option would be to return to his own realm and disappear into nothingness like everyone else who had died during the war. It was about as much of a foregone conclusion as it sounded. And he would be lying if he said that he wasn't at least tempted by the thought of being reborn into a new world where being "Uchiha Sasuke" didn't mean anything, where he could be just another person in a crowd.

"What about the language? I can understand what you're saying right now, but will I be able to understand the people of your world?" he asked with curiosity.

"You will," Eris said quickly with an affirmative nod of her head. "Upon your transfer, your brain will be overloaded with information about how to speak, write and read the languages of our world as if it was your own."

For a moment, the girl seemed to hesitate whether or not to bring up what she was going to say next, but a quick look into Sasuke's eyes let her know that she wouldn't be able to lie to him and that she should just tell him. "There have been occasions when an individual's brain hasn't been able to handle the influx of information and have... uh, gone 'poof', b-but I'm-sure-that-won't-be-a-problem-for-you!"

She said the last part very quickly before looking away from him, refusing to meet his eyes. Instinctively, Sasuke wanted to question exactly what she meant by 'gone poof' but instead, he just shook his head and let the matter drop. It didn't really matter what it meant. He was already dead, and if he wasn't going to accept her offer to be reborn into her world, he would just fade into nothingness anyway so it wasn't like he had much of anything that he could lose to start with. Instead, he moved on to the next thing on his mind.

"What about my chakra and all my jutsu?"

Discreetly letting out a sigh of relief that he hadn't questioned her further about the topic, Eris turned back to face the shinobi. "Well, we don't have chakra in our world, but we do have a similar concept called 'mana'. When your body gets translated to fit in our world, your chakra should be replaced by equal amounts of mana. Similarly, you should be able to cast any of your jutsu as usual by using your mana as a source."

Here, Eris made a pause in her monologue to make sure that Sasuke was still following. And while he was a bit curious about how this 'mana' was different from the chakra that they had in his world, he signaled for her to continue. It didn't sound like it would be a problem, and as long as it didn't hinder him in his quest to defeat the Demon King, he didn't really care too much about it. He had never been one to overthink things during his life, so why start in the afterlife?

"That, coincidently, lead us nicely into another topic that we need to discuss," Eris said cheerfully, as she reached behind her back and produced what appeared to be a large catalog of some kind seemingly out of thin air. "Every adventurer who is chosen from another world to take on the quest to beat the Demon King is allowed to bring one item of their choosing with them to our world. It can be an item from your world that you're particularly fond of, or you could choose an item or a skill from our suggestions in this catalog."

That caused Sasuke to blink. He had assumed that he would just be thrown headfirst into this new world with nothing but his wits and the clothes currently on his person, but upon second thoughts it did make sense that the gods would want to increase the chance that someone they sent to defeat the Demon King would be successful. Accepting the large catalog without a word, he flipped it open and began to quickly skim through the index that covered the book's contents.

His first thought was the bring along his Sword of Kusanagi that he had lost during Team Seven's battle with Ootsutsuki Kaguya. It had served him well for years and had become such an integral part of his fighting style that he had admittedly felt a bit naked facing Naruto without it during their final battle at the Valley of the End. However, he quickly dismissed the thought. While it had undoubtedly been a very well made sword, the only reason he wanted that specific sword was for sentimental reasons, and he was certain he would be able to replace it without much trouble once he was in the new world.

For a brief moment, he considered whether there was anything in Eris' catalog that could possibly enhance his combat abilities in any useful way before his mind zoned in on a specific part of the goddess' previous statement.

"Hey, what do you mean when you say 'translated'?" he said as he looked up to meet the white-haired girl's eyes.

Eris blinked in surprise, apparently not having expected this question, but answered anyway. "In order for you to be reborn into our world, we will have to create an entirely new body for you, since your old body is still left in your world. In order to accomplish that, a new body will be created based on your genetic code, adapted to live in our world to make sure there are no unfortunate repercussions."

That made sense. However, that was also what he had been worried about.

"What about modifications that have been made to my old body during my life?"

While the addition of the Sage of the Six Path's chakra was the most recent on the long list of modifications that had been done to his old body, that list also included things like his immunity to poison that Orochimaru and Kabuto had bestowed upon him and, most importantly, the Eternal Mangekyo Sharingan that he had gained from the transplantation of his brother's eyes.

"Eh, I'm not entirely certain how that would work, to be honest." Eris put a finger to her chin in thought. "If the modifications didn't change your genetics, then I would guess that they wouldn't be transferred to your new body. Was there anything in particular that you were thinking about?"

Despite his reluctance to share such sensitive information about his clan with someone who wasn't a part of it, Sasuke only hesitated for a moment before he began to explain why this was such a big deal to him. If he were to start a new life in this world, he needed to know if his inherent abilities would cause an issue. The Mangekyo Sharingan itself was a natural genetic occurrence in an Uchiha who had experienced a certain level of mental stress, as had been explained to him by Senju Tobirama, the Second Hokage, towards the end of the war, so he felt pretty certain that he would retain that ability, regardless of what body he was in. The Eternal Mangekyo, however, had a physical requirement that had to be met for it to exist, namely the Sharingan of an Uchiha other than himself. As such, if he were to lose his brother's eyes, then he would eventually go blind.

"O-oh, erm... I see." Eris said after he had explained the secret of the Eternal Mangekyo Sharingan to her. She seemed slightly disturbed by the thought of someone taking their sibling or parent's eyes for their own gain, but tried to not show him how much the thought disturbed her. Keyword 'tried'. "W-well, I'd guess that you would lose your Eternal... what was it called? 'Manicure Sharing-Gun?' once you were reborn in our world since you wouldn't have your brother's eyes."

Hearing her butcher his clan's ability caused Sasuke's left eye to twitch dangerously. Even Naruto hadn't managed to mess up any of the Uchiha Clan's ability names that badly, and he had been known for not being too quick on the uptake, especially when they were kids.

"Well then," he said, coughing loudly into his hand in an attempt to ignore the girl's inability to pronounce his clan ability's name correctly. "I don't wanna go blind after a few months in this new world, so I guess that settles it. The 'item' I choose to bring with me to your world is the eyes of my brother, Uchiha Itachi."

Eris actually had the decency to look embarrassed at having mispronounced the name of his ability, however, she quickly straightened out her features again and nodded in acceptance of his request.

"Very well, then your request shall be granted," she said as she once again reached behind her back and produced an item seemingly out of nowhere, this time a small pouch containing a small number of coins if the clinking sound was anything to go by. "Then, unless you have any more questions, the only thing left to do is to give you this gold to spend as you would like, and send you on your way."

Absentmindedly accepting the coin purse from the Goddess of Fortune, Sasuke wracked his brain for anything else he wanted to ask before he left on this new adventure.

"I think I'll be fine. Whatever happens, I'll deal with it when it comes up," he said, feeling a strange tugging at his lips as he realized how much like his rival he sounded when he said it.

As if his words had been a trigger, a magical emblem appeared underneath his feet the moment he finished speaking. The bluish glow that emanated from the runes that were etched around the outer part of the circle almost blinded him, and he instinctively reached up to shield his eyes from the light. A second later, he felt his feet leave the ground.

"Then I wish you good luck on your quest, Sasuke." Eris' voice sounded from somewhere below him, causing Sasuke to look down toward the white and blue figure that was steadily growing smaller the higher into the air he floated. "Oh, and if you do manage to defeat the Demon King, the gods will reward you by granting you a wish of your choosing!"

The surprise from that last tidbit of information somehow managed to cause Sasuke to stumble in mid-air.

"How come you've waited this long to tell me that?!" he called back to the goddess who was waving innocently towards him and smiling mischievously.

Before the goddess could answer though, another magical emblem appeared a few feet above his head, this one presumably acting as the portal that would send him to Eris' world. With one last glance towards the still grinning goddess, Sasuke sighed and turned his attention towards the emblem, towards his future. In the end, it didn't matter that she hadn't told him about the possible reward for defeating the Demon King; he had chosen to take on the quest anyway. Had that been the whole point of not mentioning it until he had already been sent on his way? He didn't know, but the thought of it caused the shinobi to smile. As whimsical as Eris had been, she clearly wasn't one he should underestimate if they ever met again.

-X-X-X-X-X-

Once the light had faded, Sasuke found himself laying on his back in a field. Sitting up and looking around, his still somewhat fuzzy mind worked overdrive to take in every part of this new world, every sound and every sensation of the world that would be his home for at least the foreseeable future. In the distance, he could see what appeared to be a city of some kind, surrounded by a large stone wall that was probably meant to protect it from whatever animals prowled these lands, as well as the Demon King's army if they ever came knocking.

Glancing over his shoulder, he found that he was sitting underneath one of the many trees that were scattered across the landscape that surrounded the town. Unlike the humongous trees that he was used to from his own world, however, these trees were only a few meters high at most. And unlike the bumpy terrain of the Elemental Nations, the area surrounding the city was almost completely flat. To Sasuke, who had never seen such a large area as flat as these plains, it felt almost unnatural.

"Well, this really is another world, huh?" he said aloud, looking down at his hand and flexing it to try and determine whether his physical abilities had been affected by the 'translation' that Eris had been talking about. From what he could tell, this new body was in good shape. Not quite as good as he had been towards the end of the Fourth Great Shinobi War, but definitely good enough that he wouldn't have to worry about overexerting it by being reckless during his first few days adapting to this new world. However, as he lifted his left hand to form a few hand seals to try casting a jutsu, his sharp eyes picked up on something else that was missing.

His summoning tattoo was gone.

Or more accurately, it had never been there, to begin with. If he was completely honest, the loss of it didn't bother him as much as it probably should have. While he had formed a mutual respect with Aoda, they didn't really share a close relationship like the one Naruto seemed to share with his toads. As for his hawk summons, the only time he had used them for anything other than transportation had been during his battle with Danzo, and he had gained other ways to increase his mobility since then so it shouldn't hamper him too much. However, that did remind him...

Not wasting another second, he rose to his feet and turned to face the city in the distance. He needed to find a water source, or any other reflective surface to confirm that he still had the Eternal Mangekyo Sharingan. Whether or not he still did would affect how reckless he could be with its' use. While he was confident in his abilities even without it, he had come to rely heavily on it to keep him and his allies alive during the war so if he didn't have the Eternal version anymore, he would need to get used to not using it unless absolutely necessary again.

With that thought in mind, he set off on a brisk walk towards the city in the distance. First off, he would determine whether he still had the Eternal Mangekyo, and then he would try to gather some information about his current whereabouts and decide what course of action to take from there.

However, he had barely been walking for more than a few minutes when his ears picked up a low rumbling sound from... somewhere below him? His mind instantly recalling Kakashi's 'test' of Team Seven from three years earlier (had it really only been three years since that day?), he dashed forward just in time to avoid being swallowed by the large gaping maw that came bursting out of the ground where he had been standing just a second earlier.

With instincts honed from a year of nothing but moving from fight to fight, Sasuke twisted in mid-air and landed gracefully a few feet away from his enemy. Without even thinking twice about it, his eyes had changed from their usual onyx black color to the black and red of his Mangekyo Sharingan (whichever form of it he currently had) and he was already half-way through a cast of Amaterasu before he caught himself.

"Tch," he gritted his teeth in annoyance as he forced himself to dispel the jutsu before it was cast. He had to restrain that reflex for now, just in case he really had lost his Eternal Mangekyo Sharingan.

Taking a deep breath to calm himself down, he turned his attention back towards whatever it was that had attacked him... and did a double take. Staring him down from where he had been standing just a few seconds earlier was a giant toad, not too dissimilar to the ones that Naruto had been able to summon. The irony of the situation wasn't lost on him.

'Is this some kind of joke by the gods?' he thought as he watched in disbelief as the giant toad leaned down and sprang forward towards him once more, giant mouth open to swallow him whole.

Waiting until just a moment before the toad came down on him, Sasuke leaped into the air and somersaulted over the toad's open maw, his hands quickly going through the familiar hand seals of his clan's signature jutsu.

"Fire Style: Fireball Jutsu!" he shouted as he felt the familiar rush of heat traveling from his lungs to his mouth before being exhaled in the form of a huge fireball that nailed the surprised toad in between the eyes.

As the flames spread to swallow the amphibian whole, Sasuke landed a few meters away. That had been almost too easy. He was pretty sure that even Killer Bee in his full Tailed Beast State had been faster than this toad. If this was the kind of monsters he would be facing from now on, perhaps he wouldn't even need the Mangekyo Sharingan...

His thoughts process was interrupted as without warning, the flames parted when the toad came flying towards him again, seemingly completely unharmed by his attack. Caught off guard by the large amphibian, Sasuke barely had enough time to dodge to the side. Just barely rolling out of the way of the large monster, he could feel the ground shake beneath his feet when the green giant landed just half a meter away from him.

Hoping to buy some time to regain his footing, his hand reached for the pouch that was tied to his belt to throw some shuriken at the toad... only to realize that the only thing that was currently tied to his belt was the coin purse that Eris had given him before he had departed for this world. A quick glance towards his wrists told him that the storage seals that he usually had prepared in case he ever ran out of shuriken had also been left behind when his body was translated. He didn't have any equipment on him at all!

Cursing his lack of attention earlier when he had been checking himself over, he desperately tried putting some distance between himself and his opponent, but the toad was surprisingly nimble for its' size. Oh, how his thoughts from earlier had come back to bite him in the ass!

"Fire Style: Great Dragon Flame Jutsu!" he shouted as he locked his hands in the Tiger Seal and sent another blast of flames towards the approaching amphibian, this one shaped like the head of a dragon. However, just like the fireball before it, the Dragon Flame Jutsu didn't even seem to slow it down, forcing Sasuke to once again throw himself on the ground to avoid getting flattened by a giant webbed hand.

Coming to a stop just below the belly of the beast, Sasuke growled in frustration and quickly went through another set of hand seals.

"Chidori Sharp Spear!"

With the sound of a thousand chirping birds, a sphere of pure lightning materialized in his hand before extending itself in a straight line and piercing through the amphibian's belly, eventually emerging through its' back. When the toad began to stagger and let out a pained croak from the attack, Sasuke's lips were drawn out into a vicious smirk as he used the blade created from his jutsu to cleave the amphibian cleanly in two halves.

His smirk quickly disappeared as the two halves of the toad fell apart and drenched him in toad innards, ruining his only set of clothes in this world. Even the usually stoic Uchiha Sasuke couldn't keep from letting out a disgusted yelp at his current predicament. There wasn't even that much blood or guts, that stuff he could handle. Had done, many times in the past. It was just... slime. Icky, sticky and smelly slime.

Covering his nose in an attempt to keep himself from throwing up, he straightened up to leave the place as quickly as possible, only to find a frightening sight waiting for him. While he had been focused on the one toad that had attacked him, many more had apparently emerged from... somewhere, presumably from the ground like the one he had just fought off.

And now he was surrounded. toads in every color of the rainbow and every size imaginable between the size of his little toe and the Hokage Monument were starring him down with hungry looks in their eyes. There had to be at least 30 of them, just waiting to pounce on him. The sight caused his left eye to twitch dangerously, itching to just throw caution to the wind and fry them all up in black flames. Was this to be his atonement for the crimes he committed in his world? An endless amount of giant amphibians trying to eat him, trample him and cover him in slime?

As he fought to hold in a cry of despair, he could've sworn that he could hear Naruto laugh at him, all the way from the Elemental Nations.

"I can offer you a chance to redeem yourself."

A/N: Greetings readers and fellow fanfiction authors! I haven't posted anything on this site for a long time now, and I really want to get back into the swing of things again. I've been struggling with most of my more serious projects (for over two years now) because I feel like they deserve more than I can currently offer them with my rusty writing, and have therefore decided to instead post something less serious to flex my writing muscles again. I'm not used to writing comedy though, so we'll see how well this goes... if any of you know me from any of my previous fics, then you know they're usually a bit more on the serious side, so this will be a completely new experience for me.

On that note, I appreciate any feedback you can give me to improve my writing, even the negative one. Perhaps especially the negative one. I can't improve if I never get told what I need to improve on.

On the subject of the fic itself, there are a few things I want to make clear. I haven't read the Konosuba light novels or manga, so anything I know from events in them I've learned through secondary sources like the Wikia or other fanfics. If you know somewhere I can get my hands on them without spending too much money on it (I'm still a poor college student), I would be thankful.

Next up, I want to acknowledge the fact that the Sasuke who appears in this story is and probably always will be a little bit OOC. In fact, that will probably be true for most of the characters, though I will do my best to keep them at least somewhat similar to their canon counterparts.

The last thing I want to cover is the fact that this chapter hasn't been proofread by anyone other than myself. I use Grammarly to try and avoid spelling and grammar errors, but it isn't a failsafe so some of the grammar may still be a bit iffy. If you find any large blunders on my part, then I'd appreciate if you could tell me so I can fix them. Now with all that being said, I hope you enjoy the story! I don't have a set update schedule, nor do I know where I want the story to go, but I'm sure we can work something out! Have a good day!
